Printer Alignment

[Rieda]

Ok here goes

Im currently Writing a POS System in VB6.its actually quite far

My printing is done on a POS Printer im using the following code that prints the data from a listview and some other controls onto the POS Printer

Printer alignment is my Problem:

ssql = "Select posprinter from [Settings] "
Ocom.CommandText = ssql
Set orec = Ocom.Execute
  Dim prnPrinter As Printer
    For Each prnPrinter In Printers
    If prnPrinter.DeviceName = orec!posprinter Then
    Set Printer = prnPrinter
    Exit For
    End If
    Next
 
'Open Till Draw
Printer.Print "A"
 
Printer.Font.Size = 9.5
Printer.FontName = "Arial"
Printer.Font.Size = 12
 
Printer.Font.Bold = True
Set orec = New Recordset
ssql = "Select * from [Company Info]"
Ocom.CommandText = ssql
Set orec = Ocom.Execute
Printer.Print orec!Coname
 
Printer.Font.Size = 9.5
Printer.FontName = "FontA1x1"
Printer.Print orec!Coline2
Printer.Print orec!coaddress1
Printer.Print orec!coaddress2
Printer.Print orec!coaddress3 + "," + orec!coaddress4
Printer.Print "Tel: " + orec!cophoneno
Printer.Print "Vat Reg: " + orec!coregno
 
Printer.Font.Size = 19
Printer.FontName = "FontA1x2"
Printer.Print " "
A$ = "TAX INVOICE"
Printer.Print A$
 
Printer.Font.Size = 9.5
 
Printer.Font.Size = 9.5
'Printer.FontName = "FontA1x1"
Printer.FontName = "courier new"
Printer.Font.Bold = True
Printer.Print "Customer      : " & txtCustomerName
Printer.Print "Date          : " & lblDate
Printer.Print "Time          : " & lblTime
Printer.Print "Sales Person  : " & lblUser
Printer.Print "Slip No       : " & InvoiceId
Printer.Print "-----------------------------------------"  'LF
 
For Each Lst In FrmPOS.lstvInvoice.ListItems
Printer.Print Lst.SubItems(1) & " "
 
Printer.Print Format(Lst.SubItems(2), "#####0") & " "
 
Printer.Print Lst.SubItems(4) & " " & Lst.SubItems(10)
Next
 
Printer.Font.Size = 9.5
Printer.FontName = "Courier New"
'Printer.FontName = "FontA1x1"
Printer.Print "-----------------------------------------"  'LF
 
Printer.Font.Size = 10
Printer.FontName = "Arial"
Printer.Font.Bold = True
 
Printer.Print "Total  :" + FormatNumber(txtTotal, 2)
Printer.Print "Cash   :" + FormatNumber(txtTendered, 2)
Printer.Print "Change :" + FormatNumber(txtChange, 2)
 
Printer.Font.Size = 9.5
'Printer.FontName = "FontA1x1"
Printer.FontName = "Courier New"
Printer.Font.Bold = True
 
Printer.Print "Thank you for your Support"
Printer.Print "Visit us: www.distinctiv.net"
Printer.Print "Email us: [email][email protected][/email]"
Printer.Print "KEEP THIS TILL SLIP AS PROOF OF PURCHASE"
 
Printer.Print ""
Printer.Print ""

Printer.Print ""
 
Printer.EndDoc
 
MsgBox "Please Remove Change and Close Till Draw"

I basically want certain things left aligned and some right aligned

for eg the numeric fields need to be right aligned so that figures line up

Welcome to the forums.

I have edited email address in your post.

Thanks.

to right align, you can use printer.currentX = to set the horizantal print position, or you can pad the numeric with spaces to make the amounts align to a decimal position
you can use printer.textwidth("$12345.66") to return the width of the printed text in the currnet font for the printer, then calculate the number of spaces required to align all the amounts to the decimal point,
if you build a function to do this you can just call it each time you want to align the text, something like this

Private Function dectab(amt As Double)
Dim myt As String, myl As Integer, maxl As Integer, strl As Integer, mystr As String
myt = Format(amt, "##,##0.00;##,##0.00")
myl = TextWidth(myt)
maxl = TextWidth("888,888.00")
strl = (maxl - myl) / TextWidth(" ")
mystr = Space(strl)
dectab = mystr & myt
 
End Function

call like

printer.print dectab(txtTotal)

you can put any additional formating you want within the function

edit: textwidth in the above function should be changed to printer.textwidth, as this function was used to print to a textbox or form, which probably would be using a different font or font size

So I needed to Print for see below:

printer.print "Total:" &  dectab(txtTotal)

What would I use to left align total and right align txttotal
Should I use printer.currentx or something to that effect

[westconn1]

use printer.currentx to set your left margin for each line. then you could use again to set the position for the amount, you would need to calculate the width of the text to the right of the decimal, deduct that from the position of your decimal, then that would be your currentx to print the amount

Printer.CurrentX = lmargin
Printer.Print "Total:";
Printer.CurrentX = decimalpointposition - Printer.TextWidth(Format(txttotal, "######0"))
Printer.Print txttotal

just another way to do it
